When I login a ftp server, and right-click a file, and select [Properties] in the right-click menu. WinSCP 576 doesn't show any data in 'Group', 'Owner', 'Permissions' label. While WinSCP 506 shows correctly!

Since 5.0.7, WinSCP uses a modern MLST command to list directories by default, instead of an obsoleted LIST.
Unfortunately some FTP servers does not provide all the details in the MLSD listing, that they do provide in LIST listing.
